under the following conditions:
In the United States, Canada, and other
countries governed by FCC guidelines,
external antennas can only be used in an
access point operating temperature range of
15° C - 40° C (59° F - 104° F). In these coun-
tries only external antennas with a gain of
up to 8 dBi may be used. This includes the
antennas listed in the table below.

If the access point is used with an exter-
nal antenna you must also purchase an
antenna cable. For maximum efficiency,
use the shortest antenna cable possible.
Antenna cables induce signal loss,
which will limit the radiated power out-
put and range of the access point. Of the
options available, we recommend the
3Com 6-Foot Antenna Cable (3CWE480).
